WNM4002-3/TR 产品概述

一、产品简介

WNM4002-3/TR 是 KUU 推出的一款小功率 N 沟道场效应管,单只器件设计用于低电流开关与信号控制场合。器件额定漏源电压为 30V,连续漏极电流 100mA,导通电阻在 VGS=4V 时为 8Ω,耗散功率为 150mW。超小型 SOT-523-3 封装适合空间受限的移动与便携设备。

二、主要参数

  • 类型:N 沟道 MOSFET(单只)
  • 漏源电压 Vdss:30V
  • 连续漏极电流 Id:100mA
  • 导通电阻 RDS(on):8Ω @ VGS = 4V
  • 功率耗散 Pd:150mW
  • 阈值电压 Vgs(th):1.5V
  • 输入电容 Ciss:13pF
  • 反向传输电容 Crss:4pF
  • 输出电容 Coss:9pF
  • 封装:SOT-523-3
  • 品牌:KUU
  • 型号:WNM4002-3/TR

三、器件特点与优势

  • 低电压控制:阈值电压约 1.5V,适合低电压门极驱动场景。
  • 低电容:Ciss、Coss、Crss 均较小,有利于提高开关速度并降低开关损耗,适合高频或快速切换信号。
  • 超小封装:SOT-523-3 体积小、适合高密度 PCB 布局。
  • 适用于低功率应用:150mW 的功耗限制提示本器件适合小电流、间歇性或低占空比的开关场合。

四、典型应用场景

  • 移动设备的信号开关与电源管理(小电流负载切换、隔离控制)。
  • 便携式传感器或外围电路中的低功耗开关。
  • 逻辑电平控制的小型继电器驱动或 LED 驱动(低电流)。
  • 作为模拟开关或电平位移元件,用于信号通断控制与保护电路。

五、使用建议与注意事项

  • 热管理:Pd 仅 150mW,空间受限的 SOT-523-3 导热能力有限。长期工作或环境温度较高时需评估结温并通过 PCB 铜箔散热或减小占空比来保证可靠性。
  • 驱动电压:RDS(on) 给出的是 VGS=4V 条件下的值,若驱动电压更低,导通电阻会显著上升,应在设计前验证实际导通损耗。
  • Gate 保护:尽管未给出 VGS 最大值,建议在门极处采用限流或 TVS 保护,避免静电或瞬态电压损坏。
  • 布局建议:门极引线尽量短,靠近驱动器放置旁路电容以抑制切换干扰;在需要较大瞬态电流的场合增加旁路或限流元件。
  • 测试验证:在目标应用中应进行开关损耗、温升与可靠性测试,确保在最大工作条件下满足寿命与稳定性要求。

六、封装与采购提示

WNM4002-3/TR 以 SOT-523-3 极小封装供货,适合 SMT 大批量贴片生产。型号后缀 “/TR” 通常表示卷带(Tape & Reel)包装,便于自动化贴装。采购时请确认包装形式与最低订购量,并核对完整数据手册以获取绝对最大额定值与典型波形参数。

总结:WNM4002-3/TR 以其 30V 耐压、低电容和超小封装,适合用于需要节省空间且工作电流不大的低功耗开关场合。设计时需重视热耗散与门极驱动条件,合理选型可在便携与消费类电子中发挥稳定可靠的作用。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
